How to calculate the battery capacity, can the car battery 60ah be changed to 70ah

The amount of electricity or discharge time that a battery discharges under specified conditions (including discharge intensity, discharge current and discharge termination voltage) is called battery capacity, and the unit of measurement of battery capacity, Ah (Ampere hour), is actually the battery that can be released to The total number of electrons used externally. How to calculate the battery capacity?

The calculation method of battery capacity: Capacity C = discharge current I (constant current) × discharge time T (hours). The working time of the storage battery is determined by the capacity and working current of the storage battery. The smaller the battery capacity, the faster the discharge and the shorter the service time. Can the car battery 60ah be changed to 70ah?

Under normal circumstances, as long as the battery voltage is the same, it is possible to change the battery from 60Ah to 70Ah. In this way, the capacity of the battery becomes larger, the starting current is larger, the starting is easier, and the use time is longer. But the original car’s 70Ah battery cannot be changed to 60Ah, because it will affect the starter. When the capacity is reduced, the starting current will be reduced, and the starting power will be reduced. In some cases, the starting ability will be weakened, and starting difficulties will occur.
